Ehrenberg, 1841

Ehrenberg, C.G., 1841: Über noch jetzt zahlreich lebende Thierarten der Kreidebildung und den Organismus der Polythalamien. Abhandlungen der Königlichen Akademie der Wissenschaften zu Berlin, aus dem Jahre 1839, Physikalische Klasse, p.81-174, pl.1-4. (From the journal it is clear that the work was presented in October 1839, published as a separate in January 1840, and published in the journal in 1841.) [This was cited in Fensome and Williams, 2004, as Ehrenberg 1840a, following indications by Loeblich and Loeblich, 1966, p.14,70 and Farr et al., 1979, p.22, that the publication date was 1840. However, it is clear from the publication that the work was read in October 1838 with additions in January 1840, but that the publication date was 1841.]
